The result model puts Coquimbo Unido at 61%, the draw at 23% and Huachipato at 16%, from expected goals of 1.84 and 0.82.
The league sets the starting point. Primera has produced over 2.5 goals in 52% of its matches, and that is where a team with no record of its own would sit.
Each side's own record. Coquimbo Unido have 10 in 19 this season (4 of 9 at home), Huachipato 14 in 20 (4 of 10 away). Those records are pulled toward the league rate with the weight of about 24 matches — enough that two or three unusual games cannot swing a rating — giving 52% and 60%.
Last season still counts, briefly. With 19 and 20 games played this season, last season's rates are still blended in and fade out entirely by game 40 — the point at which our testing showed they stop adding accuracy. A single season is part luck, so each club's record is first pulled toward the league average by 34 games' weight. That moves the two figures to 50% and 57%.
The mix. Weighted 40% home side, 40% away side and 20% league — the split that beat every alternative across 30,582 matches of testing — that gives 53%.
Head to head. These sides have met 5 times in three years, producing over 2.5 goals in 60%. That nudges the number 5% of the way toward the head-to-head pattern — deliberately small, because fixtures change more than reputations do — landing on 54%.
Goal expectation. Separately a Poisson model built from attack and defence strength — using real expected-goals data where the league has it — puts this match at 50%, from expected goals of 1.84 for Coquimbo Unido and 0.82 for Huachipato. Folding in 30% of that view gives 53%.
This breakdown is generated from the same inputs the rating uses, so it cannot describe a calculation we did not perform. The full model is set out in the methodology.
